Assessment of Geochemical Reactivity in Geologic CO2 Utilization and Storage Systems 

Iloejesi, Chidera (2022-08-08)
Increasing atmospheric carbon dioxide concentration is a consequence of increasing energy consumption. As a result, developing ways to manage excess CO2 emissions has become a vital concern to avert the exacerbating effects ...

Biotransformation of Perfluorooctane Sulfonamide (FOSA), 8:2 Fluorotelomer Alcohol (8:2 FTOH), and 6:2 Fluorotelomer Sulfonate (6:2 FTS) in Aqueous Film-Forming Foam (AFFF)-Impacted Soils under Oxic and Anoxic Conditions 

Yan, Pengfei (2022-12-05)  ETD File Embargoed
The use of aqueous film-forming foams (AFFFs) for fire suppression over decades has resulted in contamination of numerous sites by per- and polyfluoroalkyl substances (PFAS). However, the environmental fate and transformation ...

Building a Sustainable Future through the Material design of 3D Printed Polymer Materials 

Shinde, Vinita Vinod (2022-05-05)
3D printing technologies are coming to the forefront of scientific, industrial, and public attention as it allows customized manufacturing of complex parts with a high degree of control over design, processing parameters, ...

Design of Copper-Based Adsorbents for Gas Separation and Purification: Exploring Novel Materials and Optimization Strategies 

Feyzbar Khalkhali Nejad, Farshad (2023-08-14)  ETD File Embargoed
This dissertation provides a comprehensive overview of the design, synthesis, and performance optimization of copper-based adsorbents for gas separation and purification. Adsorption, a cost-effective separation technique ...

Enhancing understanding of mineral accessible surface area to improve simulation of mineral reaction rates in porous media 

QIN, Fanqi (2021-07-19)
Geological formations have great potential for large scale carbon sequestration, where the CO2 is mineralized through geochemical reactions. These reactions are rather complex and can potentially alter the formation ...

Evaluation of Subsurface Gypsum-rich Rock in the Context of Geologic Carbon Sequestration 

Newsome, Jamie (2023-11-29)
Geological carbon sequestration is a promising means of reducing atmospheric carbon dioxide emissions by capturing CO2 gas and storing it long term in subsurface porous rock. The goal of geologic carbon sequestration is ...

Geochemical Modeling Study of Shale–Brine–CO2 Interaction 

Turkes, Ozan (2021-05-04)
A promising large-scale mitigation option for reducing CO2 footprint is Geological Carbon Sequestration (GCS) in depleted oil and gas reservoirs and deep saline aquifers. This study investigated the interaction between CO2 ...

MACHINE LEARNING BASED MINERAL CHARACTERIZATION FROM PORE TO CORE SCALE AND IMPLICATIONS FOR GEOCHEMICAL REACTIVITY 

Asadi, Parisa (2022-11-29)
Geological formations have great potential for large-scale carbon sequestration to reduce the net rate of increase in atmospheric CO2. In these systems, CO2 is injected into formations and mineralized through geochemical ...

Pore network modeling of reactive permeability 

Steinwinder, Jeffrey (2019-04-16)
Geochemical reactions, such as those that occur during storage of carbon dioxide in saline aquifers as part of carbon capture and storage (CCS) mitigation techniques or long-term subsurface mineral weathering, can significantly ...

Pore Scale Methods to Enhance Understanding of Geochemical Reaction Rates in Porous Media 

Anjikar, Ishan (2019-07-23)
Geochemical reactions play an important role in subsurface systems such as in contaminant fate and transport, chemical weathering and geologic carbon sequestration. These reactions, mainly dissolution/precipitation, will ...

Role of mineralogy in controlling fracture formation 

Brunhoeber, Olivia (2021-04-28)
Geologic CO2 storage systems rely on impermeable caprock layers to prevent fluid leakage and maintain system integrity. In these systems, mineral dissolution and precipitation reactions controlled by the reactivity of the ...
